Gastric ulcer. The stomach has been opened to reveal a sharply demarcated, deep peptic ulcer on the lesser curvature.

Duodenal ulcer. A sharply punched-out peptic ulcer of the duodenum is situated immediately below the pylorus.

Fig GI 10-10 Peptic ulcer disease. (A) Large incisura (black arrow) simulating a filling defect on the greater curvature. The incisura is incited by a long ulcer (white arrows) on the lesser curvature. (B) Double pylorus. The true pylorus and the accessory channel along the lesser curvature are separated by a bridge, or septum, that produces the appearance of a discrete lucent filling defect (arrow).
